BOX-COVERING MACHINE Specification of Letters Patent.

Application filed February 29, 1908.

Patented Dec. 15, 1908.

Serial No. 418,562.

To all whom fit 'may concern:

. Be it known that l, FRANK J. GERsDoRF, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented new and useful Improvements in Box-Covering Machines, of whichthe following is a specification.

This invention relates to box covering machines, and the object of theinvention is to provide a device of this character whereby a coveringapplied to the sides and ends of the box may be turned over the edgesand the covering applied to the sides and ends of the inside of the boxby a single operationl of a ever.

Another object of the invention is to provide a device of this characterwhich may be operated by either a hand or foot lever with equalefficiency.

With these. and other objects in view the invention resides in the novelconstruction of devices and their arrangement in operative combination,hereinafter fully described and claimed.

In the drawings, Figure 1 is a central longitudinal section of a boxcovering machine constructed in accordance with m invention. Fig. 2 is ahorizontal sectional view upon the line 2 2 of Fig. 1.

In the accompanying drawings the numeral 1 designates the top of asubstantially rectangular bench or table,being provided with suitablelegs or supports 1, by which it is elevated from the ground. The benchhas its top provided with a substantially rectangular openin 2, of asize slightly greater than that of the ox upon which the device isadapted to operate. Positioned within this opening 2 is a table 3,having a depending spindle 4, mounted in a hollow head. 5 of a bracket6, secured upon the bench 1. The head 5 is provided wlth a suitablethreaded oriiice adapted for the reception of a threaded member 7,adapted to contact with the spindle 4 and to retain the table 3 in anydesired position in relation to the top of the bench 1.

Slidably mounted in guides or bearings 8, upon the top of the bench 1 isa ring 9, having its inner periphery provided with a plurality ofrounded cam faces 10, the purpose of which will hereinafter be fullydescribed. The bench 1 is also provided, within the ring 9, and adjacentthe edges ofthe cut away portion 2, with spaced guides 11 arranged inpairs opposite each of the walls of the cut away portion 2, and adaptedfor the reception of sliding blocks 12. These blocks 1.2 are providedupon their inner ends with an up turned portion 13, and secued to thetop face of this up turned portion is an edge turning plate 14. I

The inner wall of the up turned portion 13 is provided with a rod 15,extending through bearings 16 rovided upon the bench 1.. The outer en ofthe rod 15 is provided with a suitable orifice adapted for the receptionof a pintle 17, and interposed upon the rod between the pintle 17 andthe bearing face 16 is a helical spring 18, adapted to normally forcethe sliding blocks rearwardly against the inner periphery of the ring 9,and the edge turning plate 14 away from the opening 2 of the bench 1.The faces of the sliding blocks 12 adjacent the inner periphery of thering 9 are rounded so as to provide a suitable. contacting face for therounded cams 10 upon the ring 9, when the ring is rotated to force thesliding blocks inwardly against the pressure of the spring 18 so as tobring the edge turning plates 14 over the box adapted to be positionedupon the table 3 within the opening 2. The squared opening 2 of thebench 1 is provided with corner guides 19. These guides 19 are providedwith suitable slots adapted for the reception of headed bolts positionedwithin the bench 1 and whereby the guides may be moved towards or awayfrom the corners of the opening 2.

Positioned upon the bench 1 is a standard 20, having a bracket 21secured to the stand ard and provided with a suitable brace 22. Thestandard 21 is provided with a guide head 23, within which is slidablymounted a rod 24, connected with a plunger 24', posi tioned above theopening 2 of the bench 1. The opposite end of the rod 24 is connectedwith a hand lever 25, having a pivoted bearing in ears 26 connected tothe upper end of the standard 20'. The rear end of the hand lever 25 isconnected with a bar 27, provided with a suitable cam face 28. This bar27 is positioned adjacent the rear of the bench 1, and its free end isconnected with a foot lever 29, pivotally secured upon a bracket 30connected with the rear of the bench 1. The table 1 is provided at therear of the standard 20 with a suitable staple 31, adapted for thereception of a torsional spring 32, which is also connected with thehand lever 25, and which serves as an eHective means for elevating thefront end of the handle and raising the plunger 24 away from the bench1, as well as depressing the cam face 28 of the bar 27 beneath the upperedge of the bench 1.

Pivotally secured to the rear of the top of the bench 1 is an arm 33,having a bracket 34 provided with a roller 35, adapted for engagementwith the cam 28 of the bar 27. The arm 33 is also provided with asuitable ear 36, adapted for the reception of a helical spring 37, theopposite end of the spring being secured in a bracket 38 provided uponthe end of the table 1. By this construction it will be seen that theroller 35 is normally contacted with the cam face 28 of the arm 27.Suitably spaced from the arm 33, and connected therewith by an inclinedlink 39 is an arm 40, pivoted to the bench 1 as at 41. The free end ofthis arm 40 is provided with a link 42 by which it is connected with anarm 43, connected with the ring 9.

The operation of my device is as follows: The box to be covered ispositioned upon the table 3, the covering being suitably gummed andapplied to the bottom and sides of the box if desired, the covering forthe edges and the sides of the interior of the box is left upstanding,having previously been cut the required length. Either the hand lever 25or the foot lever 29 is operated, causing the cam 28 to contact with theroller 35, thus swinging the arm 33 upon its pivot and forcing its freeend inward against the pressure of the spring 37. The opposite end ofthelarm 33 carrying the link 39 moves-thc arm 4() upon its pivot 41,which in turn moves the arm 42 and the arm 43 connected with the ring 9,thus causing the ring to rotate within the guides 8 and the cams 1() tocontact with the rounded faces of the sliding blocks 12, forcing theedge turning plates 14 against the edges of the covering of the box.When the cams 10 have been rotated past the sliding blocks 12, thesprings 18 connected with the rods 15 will force the blocks rearwardlyagainst the inner periphery of the-ring 9, thus retracting the edgeturning plates to their original position. The plunger24 is nowdescended within the box causing the gummed faces of the covering toadhere to the inner sides of the box. When pressure is released fromeither the hand lever 25 or the foot lever 29, the spring 32 will forcethe plunger upwardly and the lower face of the cam 28 again intoengagement with the roller 35 when the ring 9 will be again rotated toreturn it to its original position. -ilThe box upon the table 3 is nowremoved, a second box and covering inserted within the opening 2 andupon the table 3, and the operation repeated.

Having thus fully described the invention what is claimed as new is:

1. In a box covering machine, the combination with a movable table and aplunger, of a bench having a cut away portion, slidable spring retardedplates upon the bench adj acent the edges provided by the cut awayportion, a ring having cam faces upon the bench, and means for rotatingthe ring to force the cam faces into contact with the plates to move theplates forward over the cut away portion of the bench.

2. A box covering machine comprising a bench having a cut away portion,an adjust able table beneath said cut away portion, spring pressedplates above the sides of the cut away portion, a plunger above said cutaway portion, means connected with the plunger for forcing the platesover the opening and the plunger within the opening after the plateshave been forced away from the opening.

3. In a box covering machine, a bench having an opening, a movable tablebelow said opening, guide plates uponsaid bench, blocks between theguide plates, plates upon saidl blocks adjacent the sides of theopening, rods upon the blocks, bearings for the rods, springs upon therods normally tending to force the plates away from the openings,adjustable guides for the corners of the opening, a ring having camsmounted in guides upon the bench, a standard upon the bench, a leverupon the standard, a plunger upon the lever, a bar having a cam faceupon the lever, a second lever connected with the bar, a spring pressedroller contacting the cam of the bar and a plurality of arms connectingthe roller and the ring, whereby the ring may be rotated by the cam uponthe bar and the cams upon the ring contact the sliding blocks to forcethe strips over the opening and the plunger within the opening after thecam upon the bar has passed the roller, and means for normally holdingthe plunger away from the opening in the bench.

In testimony whereof l affix my signature in presence of two witnesses.
